Nice game. I especially like the art style and and the music which fits very well together. It was a bit hard to hit the sparks, but this might also be just my computer which is not the most powerful. Maybe the reason was, that the feeling for space was at least for me not so good. Hard to say why, maybe because you are floating in a big empty room with only the sparks. Not sure if it would help if you have some more solid items in the play area.
Still this is a solid entry. Congratulations!
